T0 aZZ whom it may concern:

Be it known that I, MYRON W. CLARK, a citizen of the United States,residing at Parma, in the county of Jackson and State of Michigan, haveinvented certain new and useful Improvements in Oonveyers for Flour-Bolts, of which the following is aspecitication, reference being hadtherein to the accompanying drawings.

Figure 1 is a longitudinal section taken on line mm, Fig. 2. Fig. 2 is'atransverse section taken on line yy, Fig. 1. Fig. 3is a detached view-ofone oi'the chutes. Fig. 4 shows a modification. Fig. 5 is a transversesection, on a diminished scale, of the lower portion of a flour-bolthaving my invention applied thereto. I

A A are the gather-boards or cant-boards, arranged below the bolt, whichis represented by A. These gather-boards are joined at their upper endsto the outer casing-walls, A A of the bolt, and inclined downwardly andinwardly toward the center-board, so as to form a longitudinal throatabove the center-board, extending practically the entire length of thebolt-chest. Each of these boards is provided upon its loweredge with aseries of transverse slots, a a.

BB Gare, respectively, the outer side boards and the center-boards,which, with the ends E E, constitute conveyor-boxes arranged below thegather-boards, whose lower edges are a short distance apart, so as toprovideathroat for the passage of material to the conveyers.

F F are the conveyers, of any usual or approved construction, having theends of their shafts journaled in the end boards, E E, or in boxessecured thereto.

G G are swinging covers hinged at the upper edges to the gather-boards,with their lower edges resting upon the upper edges of the side boards,B B.

H H are partition-bars, substantially triangular in cross-section,arranged at suitable intervals, with their ends supported upon thecant-boards. Each bar is slotted longitudinally upon its under side, asat h, the bars being so arranged upon the cant-boards that each slot hcoincides with two slots, a, in the gather-boards, for a purpose whichwill be explained.

I I 1 indicate, respectively, the bottom and sides of the vibratingchutes. Each side portion, I,is of substantially triangular shape, andarranged at a right angle to the plane of the bottom portion, I. g

t i are holes for the reception of bolts 0, by means of which the chutesare suspended from the partitionbars H H, in such position that theedges of the triangular sides I I can be inserted in the slots a whenthe chutes are in the position shown in the drawings, and are thereforeinproper working relation to the cantboards and the conveyers, thusinsuring that no material can pass down between the upper edges of thesides of the chutes. By an examination of the drawings it will bereadily understood that the bottoms I of these chutes form practicallycontinuations of the cantboards, and that they (the chutes) can bearranged to deliver material to either of the conveyers alternately.Thus when the end of a chute is placed in contact with or in closeproximity to the under surface of the cantboard A, such material aspasses on to the I chute will be delivered to the conveyor F, and

vice versa. In my invention the upper edges are formed on straightlines, and therefore the blanks from which the chutes are made may eachbe bounded by straight lines, and the chutes may be pivoted to thepartitionbars by the use simply of bolts or pins passing through holesin the bars and through the upper corners of the sides of the chutes. Ido not wish to be limited to forming the partitionbars and the loweredges of the gather-boards with slots in them, because under somecircumstances they might be dispensed with, and the chutes pivoted toears h projecting downwardly from the bars, as i11- dicated in Fig. 4,although I prefer the construction shown in the other figures, because,among other things, the friction between the sides of the chutes and theadjacent walls of the slots assists in maintaining them in properposition after they have been adjusted by the operator. It will ofcourse be understood that in either construction shown the contiguousportions of the sides of each pair of chutes may be so pressed upon eachother by means of the bolts and nut-s c as to produce this desiredfriction.

I am aware that Patent 27 7,547 to Cottrea'll shows vibrating chutes incombination with inclined gather-boards or cant-boards and two conveyersunder a construction and arrangement somewhat similar to mine; but myinvention differs materially from that of Cottreall, in that, amongother things, his chutes are pivoted directly to the upper edge of thecenter-board, which is placed between his two conveyers, each pivotbeing arranged about midway between the ends of the flat surface orbottom of his chute, so that when in operation one half of each chute'projects downwardly below the line of the upper edge of thecenter-board, while in my construction each chute is suspended uponpivots, which are so far above the center-board that the chute swingsfree of the center-board, and the opposite ends of the chute engagealternately with the center-board and the lower edge of one of theinclined cant-boards.

What I claim is- 1. The combination, with a flour-bolt, of two conveyersarranged side by side, a centerboard between the conveyers, and anadjustable chute provided with upwardly-projecting sldes and pivoted byits sides above its bottom, whereby the opposite edges of its bottom maybe alternately elevated to receive material, and a hopperbottomedchamber between the chute and the bolt to receive material and deliverit alternately to opposite sides of the chute, substantially as setforth.

2. The combination, in a flour-bolt, of two conveyers arranged side byside, a center board between the conveyers, an adjustable chute, and ahopper-bottomed chamber between the chute and the bolt' to'receivematerial and deliver it to the chute, said chute being adapted to retainits position by friction after adjustment, substantially as set forth.

3. The combination,with a flour-bolt, of two conveyers arranged side byside, a center board between the conveyers, a series of adustablechutes, each provided with upwardlypro ecting sides, a series ofsupports for the chutes arranged intermediately between the ends of theconveyers, the sides of the chutes with the supports, substantially asset forth.

4. The combination,withafiour-bolt, of two conveyers arranged side byside, a centerj board between the conveyers, a series of ad justablechutes providedwith upwardly-pro and pivots connecting i jectingsides, aseries of, transverse bars arranged intermediately between the ends ofthe conveyers, and pivotal supports connecting the chutes with the bars,the bars being of greater width than the spaces between two adjacentsides of two adjacent chutes, substantially as setforth.

5. The combination,with a flour-bolt, of two conveyers arranged side byside,,a centerboard between the conveyers, gather-boards connected withthe outer casing and inclining downwardly and inwardly toward thecenterboard,so as to form alongitudinal throat above the center-board, aseries of transverse bars supported upon the lower portions of thegather-boards, and a series of adjustable chutes, each provided withupwardly-projectingsides and pivoted by its sides to the under edges ofthe transverse bars, whereby the opposite edges of the bottoms of thechutes may be alternately elevated to receive material directly from thegather-boards and deliver it alternately at the opposite sides of thecenter-boards, substantially as set forth.

6. The combination,with a flour-bolt, of two conveyers arranged side byside, a centerboard between the conveyers, gather-boards connected withthe outer casing and inclining downwardly and inwardly,so as to formalongitudinal throat above the center-board, a series of transverse barssupported upon the lower portions of the gather-boards and having theirlower sides grooved longitudinally, and a series of adjustable chutes,each provided with upwardly-projecting sides and pivoted by its sideswithin the grooves of the transverse bars, substantially as set forth.

7. In a bolting-chest, the combination of the partition 0, whichseparates two contiguous parallel conveyer-troughs, the hopper, andcross-bars H in the bottom of the hopper, located centrally above thepartition, and the oscillating chutes I I, pivoted directly to thecrossbars and arranged to swing sothat their ends shall rest alternatelyabove the partition and below the under side of the hopper,substantially as set forth..

In testimony whereof I aflix my signaturein presence of two witnesses.

MYRO N CLARK.
